REI'RIGERATING APPARATUS Application filed December 29, 1927. Serial No. 243,421.

This invention relates to refrigerators having conduits for carrying fluids, such as refrigerating mediums or liquids condensed Within the refrigerators.

An object of this invention is to provide a lining having a channel for the reception of one or more such conduits.

Another object of this invention is to provide a refrigerator having a lining which is provided with an indented channel for the reception of one or more fluid conduits, said channel presenting a neat appearance.

Another object of this invention is to provide a lining for a refrigerator provided with a channel for the reception of one or more fluid conduits permitting the use of insulating slabs without the necessity of cutting channels in the insulating slabs.

, Further objects and advantages of the present invention will be apparent fromthe following description, reference being had to the accompanying drawings, wherein a preferred form of embodiment of the present invention is clearly shown.

In the drawings:

Fig. 1 is a vertical cross sectional view partly in elevation taken from the front of a refrigerator embodying my invention.

Fig. 2 is an enlarged vertical cross sectional view taken at right angles to Fig. 1.

Fig. 3 is an enlarged detail cross section taken along the line 33 of Fig. 1.

Fig. 4 is an enlarged detail cross sectional view taken along the line 44 of Fig. 2.

A refrigerator generally designated as 20 and embodying my invention may be provided with a cooling unit generally designated as 21 shown in this embodiment as of the flooded type having float chamber 22 provided with ice tray sleeves 23 inside of the coils 24 depending from the float chamber 22. A refrigerant line 25 may feed liguid refrigerant into the float chamber 22 an its admission may be controlled by a float valve,

' not shown, within the float chamber. A refrigerant return line 26 may receive the evaporated refrigerant from the evaporator 21 and ma return the refrigerant to the other parts 0 the refrigerating system, not shown. A drip tray 27 may be placed within the refrigerator to catch any falling water condensed within the refrigerator, and the drip tray may be provided with a drain 28 leading to any convenient point of disposal. The refrigerator may be provided with alining 30 which may be-conveniently attached to the door frame 31. This lining may have a channel 82 formed in the lining, and it may be formed by indenting the lining thruout all of the one dimension of the lining, as for instance, the vertical dimension, as shown in the drawings. The channel 32 may have an opening 33 at some point along its length and fluid conduits such as the re-frigerantlines 25 and 26, and the drain pipe 28, or any conduit necessary in the construction of the refrigerator, may be placed along the channel 32, and, where necessary to pass from one side of the lining to the other, an opening 33 may be provided for the conduit. 7

When insulation of the slab type, such as corkboard, and herein designated as 34, is used, it may be placed against the lining 30 and because of the construction of the channel 33 it may lie against the lining without disturbance of the conduits running along the channel.

Other parts of the refrigerator herein shown are the door 410 and the casing 41, for partitioning the evaporator 22, and shelves 42. v

While I have shown as cooling means an evaporator it is to be understood that other cooling units are contemplated and that the invention is not limited to a refrigerator of the evaporator type.

What is claimed is as follows:

1. A refrigerator having insulation and a lining therein, a channel adjacent the insulation inwardly indented in said lining thruout one dimension and having an opening and a fluid conduit extending in said channel thru part of its length and passing thru said opening. v

2. A refrigerator having a lining provided with a channel indented therein, said channel having an opening, and a conduit running along said channel and passing thru said opening.

3. A refrigerator having insulation and a along sai least through lining therein, said lining havin ,a channel formed on the outer side 'of sai lining adjacent the insulation b inwardly indenting said linin and a fluid conduit extending channel.

hannel outside said lining at part of the length of said In testimony whereof I hereto aflix my signature.

WILLIAM C. HOLBROOK.
